Q:Central air-conditioning is not the thicker the better?
Not so, the air conditioning copper tube thickness is matched, small air conditioning with big copper tube can not, big air conditioning with small copper tube also not.The operation of refrigerant in the central air conditioner determines the use effect directly, so the quality of refrigerant copper tube is very important. The traditional R22 refrigerant (Freon) tube pressure is generally about 20 kilograms, and R410 new refrigerant, the pipe pressure reached 40 kg. Therefore, the central air conditioner that uses new refrigerant needs to choose better refrigerant copper pipe. Note: 410A environmental protection media require copper tube wall thickness to be thick enough.The installation of refrigerant copper tubes is the most important part of the installation process of central air conditioning. 1. All welding points shall be welded at the joint of the copper pipe and the branch pipe. There shall be no welding between the copper tube and the copper pipe. 2, in the welding process, must be in the copper tube into nitrogen (nitrogen welding process), this makes the copper pipe inside the air, avoid welding, so that the inner wall of carbon, so in the formal operation into the compressor and failure. 3. After welding, the high pressure nitrogen shall be used to blow ash in the pipe to keep the copper tube clean.Then nitrogen and pressure, this is the completion of welding must be carried out on the copper pressure test, to the copper tube filled with a certain pressure of nitrogen for holding pressure, the general pressure test time is 24 hours. It should be noted that the use of R410 refrigerant, you need to keep the pressure of 40 kg, R22 refrigerant, you need to keep the pressure of 20 kg. Nitrogen is an inert gas with a small coefficient of expansion. There is almost no change in pressure due to thermal expansion and cold contraction. If there is a decrease in the pressure gauge during the test, check that the refrigerant pipe is welded.
Q:The air conditioner can be installed on a brass 1.5 air conditioning on it
I am also just bought 1.5 beautiful inverter air conditioner, just arrived today. Is a brass, 3 meters long, in the hands of very light, really doubt is aluminum. 1 copper tubes and 1.5 pieces can be used in general, but they will definitely affect the flow of refrigerant. Otherwise, an air conditioner like 5 does not need to be fitted with a thick tube. This phenomenon seems to be widespread, my air conditioning is another relatively kind, very thick brass 5 meters, and other brands of the same period with the number of horses are very fine piece of brass.
Q:How much is the copper tube for the air conditioner?
The copper tube in the air conditioner is good. Generally speaking, the meter is calculated. That is to say, how much is it per meter?. The price of one meter varies from 20 to 40 yuan.If it's a scrap, it's between 15 and 30 yuan.
Q:Is there anything in the copper tube of the CPU radiator?
This is a heat conducting liquid, which does not do anything below 35 degrees. At 35 degrees above, the liquid vaporizes and expands (leaving some space in the tube) to heat very quickly. Some people use this stuff for heating.
Q:Air conditioning outside a copper pipe with water droplets, only with no water drops, how is it?
There is no water because it is not very cold and the amount of refrigeration is not enough.
Q:When the air conditioning installation, first screw 2 copper tubes in the exhaust? How to exhaust? Say specific points
First tighten the tube high pressure pipe joint [], then loosen the angle valve tube, a small number of horses air conditioning exhaust 5 seconds, air-conditioning exhaust for about 10 seconds, and then tighten the thick pipe [] low pressure pipe joints, the high angle valve, low pressure pipe all can be opened.
Q:If the air conditioner is re assembled, will it damage the copper tube?
Influential。 Depending on the location of the copper tubes, the effect on the air conditioning is different.When the air conditioner indoor and outdoor machine connecting copper pipe bend, air conditioning and refrigeration system piping "pressure loss" will become large, from the compressor working point, variable pressure loss large led directly to the air conditioning compressor capacity output of small systems, such as air conditioning compressor is 2 horsepower capacity, due to internal and external connecting pipe bending machine fold to a certain extent lead to evaporation pressure air conditioning system is reduced, the compressor habit pressure is reduced, the corresponding proportion of the output capacity of the compressor capacity may become smaller, 1.8 horses or even lower number of horses compressor value.When the air conditioner indoor and outdoor machine bending connecting copper pipe to a certain extent, if we can repair the best, it can not be repaired, can only replace the connecting copper pipe or the bending place on both sides are connected by pipe cut to brazing.
Q:GREE air conditioner in connection with copper to test machine
Can not try; not even copper tubes, air-conditioning can not function properly, only the internal fan rotation, can not test whether the refrigeration;
Q:What does "59" in the copper tube H59 mean?
59 represents diameterCopper tube is also called copper tube. A tube of non-ferrous metal that is a pressed and drawn seamless tube.
Q:What are the advantages of a copper tube radiator over other radiators?
Tube convection radiator can be considered from the following 5 aspects: (1) tube convection radiator appearance and fine processing, high quality products of steel plate stamping molding shell cooling after surface spray treatment, high strength, beautiful appearance, can be removed from the customer decoration housing use wood shell radiator cover. (2) energy-saving product is light, small volume, convenient construction and installation for the domestic equivalent volume of copper pipe convection radiator heat loss minimum, for customers to save a lot of space, saves the construction area and improve the utilization rate of the room, saving the purchase cost, light weight, reduce the building load.
